On one hand, increasing in prices might result in a negative impact to an economy. Because value added tax is added directly to the final price of petrol, thus people have to pay extra to fill their gas tank. For this reason, it will push the cost of logistic activities, increase the cost of living, and lead to an inevitable inflation. For example, the war between Ukraine and Russia creates an oil supply shock that breeds global market inflation; many products' price is up by 30 percent causing hardship to many people.
